WINDOW-SEALING- DEVICE.

Specification of Letters Patent. 3

Patented J an. 19, 1915..

Application filed April 12, 1913. 1 Serial No. 760,588.

To all whom it may concern."

Be it known that 'I, ALVAR K. Tnnns'rnnr, a subject of the King of Sweden, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Window-Sealing Devices, of which the following is a specification.

My present invention relates to window sealing devices and particularly to means for sealing the window sill space in carriage Windows.

The invention is particularly useful for and will be described as applied to carriage windows but it will be understood that it might be applied equally well to other types of windows and that the invention is not limited to any particular type, a carriage window and its associated parts being described for purposes of illustration only.

' The object of'the invention is to provide a simple, inexpensive and effective means for sealing the space between the outside of the window and the sill to prevent rain, snow, &c., from entering the well that receives the window when it is lowered and at the same time toprevent rattling of the window when closed.

This invention is particularly applicable to the forms of sashes that are arranged to travel in a vertical plane only, in contradistinction to those'that also move transversely over or against the weather rail.

This invention consists in the novel parts, combinations of parts and details of construction of the window sealing device hereinafter more particularly described and then specified in the claims.

In the accompanying drawings, Figure 1 is a transverse vertical section through a carriage or automobile door having my' invention applied thereto. Fig. 2 is an enlarged section taken on the line 2-2 Fig. 1. Fig. 3 is an enlarged cross-section through a sealing device constructed in accordance with this invention and showing the same in operative position. Fig. 4 is a similar view showing the parts in position taken when the window has been opened a short distance. Fig. 5 is a cross-section through a modification.

The door illustrated in the drawings comprises a casing 1 having a sill 2 and a hollow well 3 that receives the sash or the window panel when lowered. The window-panel 4 slides vertically in suitableguides formed in the side of the frame 5, said frame surmounting the casing 1 as is usual. The closure for the window space preferably con sists of a panel of glass 4 without any inclosing frame, this being the latest improved type of sash for automobile use.

6 indicates a U-shaped metallic trough running the width of the window panel 4 and in which the lower edge of the panel is seated, the glass being secured therein by a suitable'cement 7 the trough 6 forming a carrier for the sash or window panel 4.

Any suitable means or mechanism for raising and lowering the panel may be employed. Preferably I employ a chain driven mechanism operated by a rotary handle-projecting from the interior side of the casing as by such construction the old form of lifting strap is dispensed with. In the such as shown and described in my prior application for patent for window operating device, filed December 19th, 1911, Serial Number 666,759. This feature forming no part of the present invention is not herein shown.

12 indicates a laterally projecting pin carried by the chain 8. The pin 12 engages a slot 13 in a plate 14 secured to and depending from the window panel carrier 6. When the handle 11 is rotated the chain 8 travels over the sprockets 9 and 10 and carries the pin 12 with it. By its connection with the plate 14, the pin 12 raises and lowers the panel 4 in an obvious manner. Preferably a coil spring 15 is provided in the sprocket 10 to counterbalance the weight of the panel and assist in raising it.

16 indicates an overhanging ledge secured to the sill 2 of the casing 1 in any desired manner on the interior. thereof and prefmaterial 18 of any suitable character as, for instance, rubber, is preferably secured to the inside of the casing 1 below the ledge 16 and in such position that it will be engaged by the flange or arm 17 when the window panel 4: is in closed position. The ledge 16 and material 17 extend from one side to the other of the opening into the well 3 and the fiange or arm 17 being coextensive therewith will, when the parts are engaged, efi'ectually seal the opening of the well 3 which is exposed to the outside atmosphere as when the window panel 4 is closed the flange 7 presses up against the material 8 in which position the Window panel is locked. The panel raising mechanism when the panel is closed positively compresses the material between the ledge 16 and the arm 17 and prevents rattling of the panel as well as sealing the well or casing. 4 7

Referring to the modification illustrated in Fig. 5, the compressible material 18, instead of being attached to the casing is carried by the window panel in its travel. For this purpose the arm 17 of the carrier is formed preferably as an integral U-shaped groove 19, said compressible material 18 being seated and secured in the groove. In this case when the window reaches closed position the material 18 is pressed against the under side of the ledge 16 and the space is sealed against the admission of any substance or matter from the outside of the window.

It will be understood that the invention is not limited to the details of construction and combinations as shown and described but that various modifications and equivalents may be resorted to without departing from the spirit of the invention as set forth in the appended claims.

What I claim as my invention is 1. A window comprising a panel and a easing into which the panel slides, said casing being provided with a projecting ledge, a U-shaped carrier in which the panel is seated provided with a projecting arm in the path of said ledge, compressible material between said projecting arm and said ledge and means for positively raising and holding the arm to compress said material when the panel is in closed position whereby the space between the panel and casing is sealed and the panel prevented from rattling.

2. A window comprising a panel and a casing into which the panel slides, said casing being provided with a projecting ledge, a U-shaped carrier in which the panel is seated provided with an integral laterally projecting arm having a longitudinal groove therein, compressible material secured in the groove of said arm and adapted to engage said ledge and means for positively raising and holding said material compressed against said ledge when the panel is in closed position whereby the space between the panel and casing is sealed and the panel is revented from rattling.

Signed at New York in the county of New York and State of New York this 9th day of April, A. D. 1913.
